POCKET CASH-REGISTER.

SPECIFICATION forming part of Letters Patent N o. 618,320, dated January24, 1899.

Application led January l5, 1898. Serial No. 666,783. (No model.)

To all whom it may concern:

Be it known that LGEORGE L. BAEKEE, of Waltham, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Pocket Cash- Registers, of which the following isa specification.

This invention has for its object to provide a compact, simple, andconvenient cash-register adapted to be carried in a pocket and used toregister different items of expense, so that travelers and others whohave occasion to spend money for different purposes while absent fromconvenient facilities for making a note of their expenditures can keepan accurate record without loss of time.

The invention consists in the improved apparatus which I will nowproceed to describe and claim.

' Of the accompanying drawings, forming a part of this specification,Figure l represents a side elevation of a cash-register embodying` 'myinvention. Fig. 2 represents a partial edge View and partial section,the view being taken from the right of Fig. l and certain parts brokenaway. Fig. 3 represents a partial edge view and partial section, theView being taken from the lower edge of l. Fig. 4 represents in separateviews the por tion of the frame of the apparatus which contains theOperatingstem. Fig. 5 represents an elevation from the side opposite tothat shown in Fig. l, showing the dial-plate and indicator shafts andpointers. Fig. G repres'ents a perspective view of a portion of thesupport or holder. Fig. 7 represents a section on line 'I 7 of Fig. l.Fig. 8 represents a section on line 8 S of Fig. l. Fig. 9 represents asection on line 0 9 of Fig. l. Fig. 10 represents a section on line 1010, Fig. l.

The same letters and numerals of reference indicate the same parts inall the figures.

My improved apparatus hereinafter described comprises a support orholder, which is here shown as a flat substantially circular plate d,having at one side a series of segmental projections cd. (See Fig. G.)Said projections are located at or near the margin of the plate a, andtheir inner sides form walls of a recess at one side of the plate, saidrecess containing the actuatinggear b. The

actuating-gear l) is mounted to rotate on a stud h', affixed to thecenter of the plate a, said stud having a head h2 at one end bearing onone side of the gear l), its opposite end being upset, as shown at b3,against the outer side of the plate a. The portion of the stud thatconstitutes the bearing for the gear ZJ is enlarged, as shown at b4, sothat the stud has a shoulder between the head b2 and the plate a, thisconstruction permitting the gear b to rotate freely between the saidhead and plate.

c c represent a series of indicator-shafts, preferably four in number,which are journaled in the plate a at one side of the actuatinggcar b,said shafts being parallel with the axis of said gear. Theindicator-shafts project from one side of the plate a and through adial-plate d, which is attached to the plate a by studs d2 and screws dand separated from said plate by the heads of said studs. The dial-plateis provided with a series of dials cl3, corresponding in number to thein dicator-shafts c and formed to cooperate with pointers c' on saidindicator-shafts.

' Each indicator-shaft c is provided between the dial-plate d and theholder a with a rig idly-fixed gear c2.

e e represent a series of connecting-gears, each of which is adapted tosimultaneously engage the actuating-gear Z1 and one of theindicator-gears c2. In the present instance the indicatorgears c2 arearranged so that their outer portions project outwardly beyond thediameter of the actuating-gear h, and each connecting-gear c istherefore made in two rigidly-connected parts 2 and 3, the larger part 2engaging the actuating-gear, while the smaller part 3 engages one of theindicatorgears. The connecting-gears 3 are movable toward and from thecenter of the apparatus, so that they can be engaged with the gears band c2 and separated therefrom. The said connecting-gears are mountedupon carriers e', which are preferably formed as levers, each connectedat one end by a pivot e2 to one of the projections d', the other endhaving a suitable projection or push-piece eS projectd ing from theperiphery of the holder and adapted to be pressed inwardly by the operantors thumb to engage'the connecting-gears e with the actuating andindicator gears. The

IOO

margin of the plate or holder d is provided with recesses c3, whichreceive the portions 2 of the connecting-gears e and permit the inwardand outward movement of said gears, said recesses being between the endsof the projections cf. The gear-carriers e extend across the recesses a3and the corresponding spaces between the ends of the projections a andare provided with hubs c4, projecting into said spaces, and in said hubsthe connectinggears e are journaled.

ff represent springs, which are arranged to press the carriers e andconnecting-gears e outwardly, and thus normally separate said gears fromthe actuatin g and indicator gears. Each spring f is preferably composedof a single piece of wire bent at its center to form a loop orbearingfl, whichis inserted in a groove a5, formed in the inner surfaceof one of the projections a', and is held in place by a pin a6, driveninto said projection and extending through the groove, the pin engagingthe loop or bearing fh Each springis therefore praetically a doublespring and bears simultaneously on two carriers c', as shown in Fig. l.The outer portions ofthe springs enter grooves eG in the hubs el, thesaid springs being thus prevented from lateral displacement.

g represents a dog, which is attached to one of the projections d andbears yieldingly against the toothed periphery of the actuating-gear I),the arrangement being such that the dog permits rotation of said gear inthe direction indicated by the arrow in Fig. l, but prevents rotation ofthe gear in the opposite direction.

7L represents an operating-stem, which is journaled in a bearingprovided for it on the holder and is provided at its inner end with apinion 7L', formed to engage the teeth of the actuating-gear Z), so thatwhen the stem 7L is rotated it will impart rotary motion to theactuating-gear. The bearings for the stem 7L are preferably formed bymaking a groove 7L2 in one of the projections a and attaching a grocvedplate h3 to said projection, the two grooves surrounding the stem 71.The stem v is provided with a squared socket h4 to receive the shank ofa pendant similar to that of a watch. Said pendant maybe detachable fromthe stem 7i, so that the device can only be op erated by the pessessorof the pendant.

It will be seen that the above-described apparatus comprises a series ofindicators, an actuator (the gear (i) common to all the indicators, buthaving no permanent connection therewith, and normally inoperativecoupling or connecting devices (the laterally-movable gears e) adaptedto connect either indicator independently with the actuator. .Vheneverthe user of the apparatus desires to register the expense incurred forany speciiic purpose, such as railroad-fares, he presses inwardly theconnecting-gear e, which cooperates with the indicator used for thatpurpose, and then rotates the actuator. lVhen the desired registrationhas been eltected, the connectinggear is released and is thereuponthrown out of gear by its operating-spring.

There may be as many indicators as circunistances may require. l havehere shown four, the dials of said indicators being inscribed toindicate that one is for registering railroads'fares, anotherhotel-bills, another payments made for excess of baggage, and anothersundries.

I do not limit myself to the details of meehanism and form of parts hereshown, as these may be variously modiiled without departing from thespirit of my invention.

llaving thus explained the nature ci my invention and described a way ofconstructing and using the same, although without having attempted toset i'orth all the forms in which it may be embodied or all the modes ofits use, I declare that what I claim isl. An apparatus of the characterspecified, comprising a support or holder, an actuatinggear, a series ofindicator-shafts adjacent to said gear and journaled in fixed bearingsin the holder, each shaft having a smaller gear and a pointer, and aseries et laterally-inevable connecting-gears, and a series ofindependently-movable connecting-gear carriers connected with theholder, whereby the eonnecting-gears may be moved into and out ofengagement with the actuating-gear, each connecting-gear being adaptedto simultaneously engage the actuating-gear and the gear of one of theindicators.
